This inventionrelates to an improved means for removabl'y connectin the end of one wire rope to the end of anot er, as in the instance of connecting a choker line to a 6 tagline 'in loggin operations, thepobject bemg to eflect suc connection in a manner that can be uickly connected and released, but is not ha is to free itself in use that i strong in its form and is free from pro 10 jections liable to encounter obstruction in The invention is fully described in the fol lowing specification, reference being made to the drawings by which it is accompanied, 16 in which:

Figure 1 'is a rspective view of the connectingmeans, t e connections being shown in dot and dash lines. a

Figure 2 is a vertical section on the line 20 2-2 in Figure 3, indicating the manner of connecting and releasing the choker line.

Figure 3 is an elevation looking in the direction of the arrow '3 in F re 2. I The device comprises alin 2 of forged floi' 'cast metal having. at one end an axial aperture 3 in which t e wire rope of the tagline 4 is relatively permanently connected by a thimbled enlargement 5- in the open space 6 between the sides of the link that will perwit the rope to lswivel freely in its cons nection. 7 1 However, as Ihave above stated that my invention relates to an improved means for ,removably connecting the end of one wire rope'to' e end of another, it is to'be un-. derstood that the. tagline 4 may nected to the upper end-of the link 2 in any. wellknown manner should a swivel connection, as illustrate be not desired. The-other end '7 o the link has a corresponding axial aperture for the wire rope 8 of the choker line, which is also provided with a thimbled end 9 for which a' chambered enlargement v link,v separated'from the space by shouldered projections 11 from each side.

From one side ofthe axial aperture of 7 is a restricted p'assage'12 that Wlll permit -the choker 8 to pass' through it, but willinot allow assage of its enlargement 9. The end-of t e chokerlinefl is connected g r v y'p 's ngxi' e ar -Ffl a the w 6 i d a s d n, W entil -tw ns e would sli ofiand movable end -8 is unlike vention, I hereby 10 is provided in the.

1 meat and extending having an axial enlargement on the o posite side and direct=- in it into the chem ring 10. J line is the essence of success in loggi-ngfi because the overhead expense. isvery great and logs from a given section must be removed with' the greatest possible speed. :I'herefore, as a matter of practicalconcern, I it is necessa that coupling and uncoupling Y be accomplis ed with aslittle man-ualattention as possible. For this. reason, itis om. mon ractice to simply 'project the cable 1 with t e enlargement through .the transverse 'openlng of the hook and, at the same time,- iive the signal to the engineer t'o 'pull' away. ence the shoulder rc'nections 11 are pref I erably formed with' tiieiruppr' faces- 11, 'inclined downwardly from the restricted pas sage 12- and -are rounded o'fl' from the'cor respondi-n front edges of the link'2fiso that, int e eve'nt 'the enlargementstrikes 76 upon the outer edges oi'the inclined shoul- Y ders W'hen tension is applied to the; cable, it be free to automatically seat within the chamber.- 1

lVith this connection, the strains are direct 0 on and between the ro e ends, and-the rey tobe accidentally disconnected from the link 2. whe'n-theline is suddenly relieved of strain. Under such conditions the thimb ledend 9. will en age and be checked by the projectionsll, w ich terminate the chambering 10, or if it es-j capes from the openside ofthe chambering', it is unlikely to be bent and withdrawn through 6.
